object thereof is to--proyide on improved.

heel- 0f some elesfiic mateiiel such es rubber which can be readily attached to-the ordinary-heel of. a hoot or shoe, e,ncl possessing superior lasting qualities and means which efiectuelly prevent slipping or skiddin With the foregoing and other objects in View. the invention consists in the novel consi/ruction combination and arrangement ,of

' parts eonstiiutingtheinventicn to be herefill inefier specificellyclescrihed and illustrated ,in the acccmnenying orewings which for-inn part hereof wherein is shown the preferred embodiment of theinvention, out 1%; is to he understood this changes, variations anilincdifications can he resorted to whichconie within the scone the matter hereinafter claimed.

"in the drawings, in which similar referencenuinerels indicate like parts in the chil fereni; figures, Figure 1, is a, perspective view of e heel looking the under face thereof; and, Fig. 2, is e longitusiinal, central, secfiional View enlergeii of the heel shown in Fig. l.

(The heel which forms the subject matter 0i": this invention comprises 9. body 1 oi an elastic material such as ruhher, having an under face 2 an an upper face 3 and with the outer edge fashioned to approximately coinci ole wi in on. leather heel. of a boot or shoe "to which it is 'co be attached Theheel is formed with a plurality OI raised integral.

lugs on the lower face thereof, the erra-ng men; of which is discretionary, and in these raised. lugs and the adjacent hocly portions are upwardly extending frusto sonically formed shallow recesses l, the open emls of which are outwardly flared and preferably arranged. concentrically with. respect to the lugs and or" such .1 size as to provide a marginnl beading: surrounding the recesses and having inclined. walls which slope up uucl IHQZQG into the under face 2 of ihe heel l. Connnunicuting with the upper portions of the recesses 4: are recesses 6 haw Specification of Letters intent.

ing lower'inclinedwalls of greater incline tion than zero, the walls of the recesses 4;

Extending upwardly from the recesses 6 and in open communication therewith ere cylindrical recesses 7 terminating near the therecesses 7 are aperturecl disks orv washers 8 the openings 9 therein being p'refcrably in alinemeno with the axes of the recesses"? The heel is secured in position by z pplying' the upper face 3 to the under side of the Patcntefl J 11Il 1.19151;

and the pointed endsfthereof are driven through the balance of the moterialwhich exists between the washers and the upper face 3 and into the leather heel by which the heel is secured.

. .n In ordinary practice the nuilsshould be so (lei-year that the heads engage end bear against the washers 8'whieh serve as abutrnents for them and she washers serve to extend the anchorage of the hea'ds'in a larger volume of rubber than would be possihleby use of the heeos alone. The heads ordinarily will be driven entirely'into thereces'ses 7 so as to leave the cup-shaped. receases e and 6 approximately unobstructed. providing the lugs on the under faceof the heel and from which the annular beadings 5 are fo'med by the recesses lgthe thickness Of e heel is increased without appreciably increasing the Weight thereof encl the capacity of the recesses are enlarged to afford s. greater suction or vacuum action when theheel is under compression and use.

Experience has shown, that when in use ihe weight ofthe wearer of the shoe will slightly'compress or distort the beads 5 enfi thereby efiecuallyfwm an approximately eight joint-with the'surface on which the shoe rests to slightly reduce the capacity of the recess so that when the heel is raised a vacuum cup action issei; up, tendingto hold the heel against slipping or skidding, espedaily on wet pavements. Furthermore, the.

provision of the lng'sirggn'which the ennuler beeuingslo {ere fornied,- .greatly increasesthe life oi? tlie'.heel' and el cltlsrip its wearing qualities and also enables it to glue n more even engagement withfsidlewalks or pavements which are irregular errough.

transverse median portions of the heel. Em bedcled in the body of. rubber by the v'ulcenization thereof at the upper termini of relatively wide fiat communicating enlargement, and an apertured Washer positioned in each enlargement and with its axis in alinement with the axis in the upper recess, said Washers providing anchorages for the heads of nails used for holding the heel in position. In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses. v
